Constant Dropping Wears the Stone

   The proverb "Constant dropping wears the stone" is well known to every one of us. It tells the truth that success is coupled with failures and difficulties, and those who have the perseverance can overcome the formidable difficulties in their pursuit.
   It is almost undeniable that success is destined to belong to those who are never afraid of trying again. The inventor of a well-known farm chemical is a good case in point. The name of the chemical, 1059, originated from the number of times its inventor had tried different ways to develop his invention. In most people's eyes, it seemed to be incredible for him to succeed, yet the inventor kept experimenting. Had he given up at the 1058th time, there would be no "1059" in the world.
   Therefore, it is true that "Constant dropping wears the stone". Perseverance is the key to overcoming difficulties. Giving up means losing everything and keeping on may bring you a golden harvest.
